Survey Report: Control Technology Evaluation for Controlling Worker Exposure to Asphalt Fumes from Roofing Kettles: Kettle Operated Using an Afterburner System at Tampa Bay Technical High School, 6410 Orient Road Tampa, Florida 33610 and West Park Villag

摘要

On September 11 through 13, 2001, two field surveys were conducted at sites where built up asphalt roofs were being installed. One survey was conducted at Tampa Bay Technical High School in Tampa, Florida where cap sheet was being installed on top of a recently installed built up asphalt roof. The other survey was conducted at West Park Village at West Chast in Tampa, Florida, a construction site where a built up asphalt roof was being installed on a new apartment/business building. The surveys were conducted to evaluate the effectiveness of an afterburner system with a safety loading door on an asphalt kettle to reduce worker exposure to asphalt fumes. The kettle used at the Tampa Bay Technical High School was equipped with an afterburner system and safety loading door, and all of the asphalt was added through the safety loading door. The kettle used at the West Park Village was not equipped with any engineering controls to reduce asphalt fume emission, and the kettle lid remained open the entire work day.
